Last Thursday, Dr. Z. and I conducted preliminary fieldwork for my Geochemistry study of the Ouleout Creek. We drove along the whole creek and made some initial observations. Dr. Z. also taught me how to use the multiprobe and how to collect water samples. We collected five samples total and collected data from the probe at four of the sites; the water velocity was too fast at one site to keep the probe safe and take an accurate reading. At each site we also recorded our geographic coordinates and elevation.
I really enjoyed going out into the field and collecting samples even though the weather was cold and rainy. We observed that the creek contains much reddish colored suspended sediment just above the Sydney reservoir and below it down to the mouth of the creek. We sampled in three locations above the reservoir; one sample came from the Ouleout Creek and two came from its main tributaries, the East Handsome and Treadwell Creek. The water was much clearer at these three sites. I will most likely research what could be causing the difference in sediment load and what effect the sediment load could be having on the water chemistry. We won't be going into the field again until the spring.
On Monday, I filtered my samples. I stored the filter paper in petri dishes. The filtered water from each site was separated into three smaller bottles. One bottle was simply refrigerated, one was frozen to preserve the anions, and the last was acidified and stored at room temperature to preserve the cations. The two samples taken below the reservoir took a very long time to filter. Other than the long wait for those samples, I really enjoyed filtering and preserving the samples, especially since the lab work was done independently for a personal research project. I was also proud of myself for realizing the first sample that took a while to filter was taking so much longer than the first two because it had much more sediment in it.
My next steps will be to start researching the geological background of the area. I will analyze my preliminary water samples after conducting some background research and constructing some hypotheses from that research. In the spring, I will develop a more complex sampling site map and hopefully start an investigation with a focused goal.

Hartwick-Hartwick Student Receives Prestigious EPA Fellowship
Hartwick-Hartwick Student Receives Prestigious EPA Fellowship
The above link will bring you to the page on the Hartwick website that contains a news piece about me. The news piece discusses the EPA GRO Fellowship I have been awarded, what it entails, and accomplishments I have so far. The Fellowship is awarded to a maximum of 40 college juniors nationwide each year, provides support for academics and research and requires the student to perform research for their junior and senior year and to complete a summer fellowship with an EPA facility.
My research will be based around the geochemistry of a small creek that is part of the Susquehanna River Shed. My advisor, Dr. Zsuzsanna Balogh-Brunstad informed me yesterday that the U.S. Geological Survey has not done any studies in this creek so my research will be all original research! I am very excited and grateful for this amazing opportunity!

Nature Knows Best -- Happy Earth Day!!
I apologize for the gap in posts! I have been super busy with school work and admissions events. I have enough tough week and weekend coming up, but I will do my best to post again soon.
Happy Earth Day!! I feel it is appropriate to talk about respecting and loving nature today. Below I talk about three points which emphasize why we should not try to fight or fix nature's "problems." Instead we should embrace natural solutions.
A common theme throughout my studies in college has been that nature knows best and nature will always win. As I briefly mentioned in my previous post about Silent Spring, Rachel Carson mentions that natural controls are the best way to deal with pests. If we use chemicals to control insect and weed pests, we are introducing harmful chemicals into the environment and speeding up the evolution of the pests we are killing. Over time, species build up a resistance to factors that are killing the species. When we spray chemicals we are forcing the species we kill to evolve at a more rapid pace, which could some day cause the "pests's" ability to survive to surpass the human ability to create or find a chemical that can kill the pest. It is better to use natural controls for pests like predators or natural pheromones that certain insects or plants, which are not harmful to our crops, that will hunt or repel the unwanted species.
I also learned about nature concurring man in my Popular Science Writing course last year. We learned about slumps, specifically rotational slumps. A rotational slump is a type of landslide in which masses of sediments move in a rotational manor. Below is a diagram of a rotational slump. We saw an example of a slump in Cobleskill on a field trip. Our professor told us that humans had cut into the hillside to create a roadway. The hill that was cut into now slumps annually, especially during wet weather, and workers have to clean up the road and put up materials to block the sediments from slumping into the road again. No matter how much effort is put into stopping the slump, the hillside continues to rotate and sediments fall. We also learned that man made or widened water ways, with steep sides in particular, will also eventually slump. Houses built above the waterway will eventually slump into the water. One house that will slump probably in 100 years or so is the Vanderbilt Mansion in Hyde Park, New York.
The last area of nature people control that I wish to discuss is agriculture. People control the land to produce food to survive. Of course, I have no problem with using the resources around us to survive, but we should do it in a more natural way. Organic agriculture focuses on building up soil quality. Soil is one of the most important parts of growing health crops. Conventional agriculture methods use chemicals that deplete the nutrients in the soil. When soil quality is decreased plants cannot get the nutrients they need and it cannot hold water as well. When soil dries out and there are few plants around whose roots usually hold the soil in place erosion can occur. If the soil quality is depleted enough, huge amounts of erosion can occur like during the Dust Bowl.
The moral of my ranting is nature has a way of taking care of itself. In time, nature will win against our modifications or our modifications will destroy nature enough that we cannot use resources the way we used to. It is best to use natural pest controls, farming methods that focus on the soil, and chose to develop the land where we do not have to make so many changes.
